which Flysky radio?
 

im about to buy flysky radio, should i go with the gt3b and do the VR mode and bearing mode or to go straight to the gt3c? the cost of the recom vr is close to the price between them.

Neither.

None. The FlySky radios are garbage and there is a reason they aren't allowed at many tracks.

Get a low end Futaba / Sanwa / KO.

i have a gt3b and its pretty good. i have other low to mid range radios and honestly its a decent radio for the cost and the receiver only costing 8 dollars is really nice

What tracks are they not allowed at?
This is a new one to me.

i know its not high end radio but its cheap and i read good reviews on it overall.
i'll go on the gt3b and do the MOD's on it.
change the voltage regulator, use lipo, firmware upgrade, and bearing to the wheel.

Ok so i just pickup i brand new gt3c that someone sold for about 35$ include receiver.
i know its no hi end unit but its build good, light, comfortable and works great!
just waiting for the Programming Unit to arrive and i'll upgrade the firmware. all and all im happy :)
